Sulphur Dioxide Analyzer

The AAQMS-500 Sulphur Dioxide (So2) analyser delivers precise and reliable performance at excellent value. It uses proven UV Fluorescence technology with standard range 0~100 ppb and 0.5 ppb detectable limit. It is CPCB / USEPA approved method and meets the latest specifications of National Ambient Air Quality Standards.

The Pulsing of the UV source lamp serves to increase the optical intensity where by a greater UV energy throughput and lower detectable concentration are realized.
